Congrats on the new puppy!

As for names how about:

Holden (as in Holden Caulfield from Catcher in the Rye...it sounds southern)
Rebel (like Aly suggested.)
Bo (You know he's just a good ol' boy...geez I'm a loser)
Forest
Billy (short for Billy the Kid)
Wyatt (short for Wyatt Eyrp)


and that's all I can think of right now.
